Hello Naser,
Please refer this wiki for the list of close activities
Month End and Year End Closing Operations - ERP Financials - SCN Wiki
On the S/4 HANA Finance side, there are new transaction for HANA e.g. KKAOH which is introduced in place of KKAO,
Other than that you month end process in S/4 HANA is quicker and hence closing process will be shortened.
Hope this helps,
